Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge scraper technology, and in particular to a centrifuge scraper device with a cleaning function. Background Technology
[0002] Centrifuges are widely used in the pharmaceutical industry. Inside a centrifuge, the drum moves at high speed, liquids are thrown out of the drum, and solids are trapped by the filter screen. The separation of materials is completed at high speed. After multiple uses, a lot of material will accumulate on the inner wall of the centrifuge drum, which needs to be scraped off in time to avoid affecting the subsequent processing of materials.
[0003] The centrifuge scraper is a key functional component of the centrifuge. It scrapes the material off the screen basket inside the centrifuge. If filter residue remains on the scraper, it will harden after drying and tear the filter cloth. Therefore, the scraper needs to be cleaned. However, the current centrifuge scrapers are cleaned manually, which is time-consuming and labor-intensive. Utility Model Content
[0004] To overcome the technical defects of the existing technology, this utility model provides a centrifuge scraper device with a cleaning function to clean the scraper that exits from the drum, thus eliminating the need for manual cleaning and saving time and effort.

[0006] Preferably, the cleaning mechanism includes a retaining frame mounted on the centrifuge body, and the retaining frame is provided with a pair of cleaning brush rollers that move in opposite directions. During the retraction of the scraper, the scraper enters between the two cleaning brush rollers.
[0007] Preferably, the retaining frame is also provided with a nozzle facing the side of the cleaning scraper, and an external water supply mechanism is also provided for supplying water to the nozzle.
[0008] Preferably, the water supply mechanism includes a water supply tank, with an outlet pipe at the bottom of the water supply tank, an inlet pipe and an air injection pipe at the top of the water supply tank, both of which are equipped with one-way valves.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model uses a lifting rod to drive the water tank of the lifting seat to rise and fall, thereby driving the scraper to rise and fall, and inserting the scraper into the drum. The first electric rotating seat causes the scraper to rotate along the inner wall of the drum, thus achieving a cleaning effect.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0020] like Figures 1-5 As shown, this embodiment provides a centrifuge scraper device with a cleaning function, including a centrifuge body 1 with a rotating drum 2. The centrifuge body 1 is provided with a scraper mechanism 3 for cleaning the inner wall of the rotating drum. The scraper mechanism 3 includes a vertically arranged positioning frame 4 on the centrifuge body 1, and a crossbeam 5 is mounted on the positioning frame 4 via a second electric rotating seat 24. The crossbeam 5 is provided with a lifting rod 6, and a lifting seat 7 is provided on the lifting rod. The lifting seat 7 is provided with a first electric rotating seat 8, and a horizontally arranged telescopic rod 9 is provided on the first electric rotating seat 8. The end of the telescopic rod 9 is provided with an elastic rod 10, and the end of the elastic rod 10 is provided with a scraper 11 for cleaning the inner wall of the rotating drum. The centrifuge body 1 is provided with a cleaning mechanism 12 for cleaning the scraper 11 after it is retracted. The lifting rod 6 drives the lifting seat 7 (water tank 16) to rise and fall, thereby driving the scraper 11 to rise and fall as well. The scraper 11 is then inserted into the drum 2. The first electric rotating seat 8 causes the scraper 11 to rotate along the inner wall of the drum 2, thus achieving a cleaning effect. The telescopic rod 9 controls the extension and retraction, allowing the scraper 11 to adhere to the filter cloth on the inner wall of the drum 2, thus providing a good cleaning effect. Furthermore, a cleaning mechanism 12 (water tank 16) is installed on the centrifuge body 1 to clean the scraper 11 after it has retracted, eliminating the need for manual cleaning and saving time and effort. The second electric rotating seat can also rotate the scraper, preventing interference with the daily operation of the centrifuge.
[0021] The cleaning mechanism 12 includes a retaining frame 13 mounted on the centrifuge body 1, and the retaining frame 13 is provided with a pair of cleaning brush rollers 14 that move in opposite directions. During the retraction of the scraper 11, the scraper enters between the two cleaning brush rollers 14. When the scraper 11 exits from the inside of the drum, the cleaning brush rollers 14 automatically clean the rising scraper, so that no manual cleaning is required.
[0022] The mounting bracket 13 is also provided with a nozzle 15 facing the side of the cleaning scraper 11, which can assist the cleaning brush roller to have a better cleaning effect on the scraper. An external water supply mechanism is also provided for supplying water to the nozzle 15. The water supply mechanism supplies pure water and will not contaminate the scraper.
[0023] The water supply mechanism includes a water supply tank 16. The bottom of the water supply tank 16 is provided with an outlet pipe 17, and the top of the water supply tank 16 is provided with an inlet pipe 18 and an air injection pipe 19. Both the inlet pipe 18 and the air injection pipe 19 are provided with one-way valves 20. The water supply tank 16 is connected to the nozzle 15 via a water supply pipe 21, and the water supply pipe 21 is provided with an electric control valve 22. In this way, gas can be injected into the water supply tank through the air injection pipe, which is used to connect with an external air injection device to inject gas into the water supply tank 16, so that a high pressure state is generated in the water supply tank 16. This eliminates the need for a pump to provide power. The use of high pressure to force water out has the advantage of being relatively fast, similar to an air pump mechanism, and has a one-way inflation effect.
[0024] The water supply tank is equipped with a pressure gauge 23 to detect the internal air pressure, which facilitates the detection of the air pressure inside the water supply tank and allows for timely pressure replenishment.
[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0026] The working principle is as follows: the lifting rod 6 drives the lifting seat 7 and water tank 16 to rise and fall, thereby driving the scraper 11 to rise and fall, inserting the scraper 11 into the drum 2. The first electric rotating seat 8 causes the scraper 11 to rotate along the inner wall of the drum 2, thus achieving a cleaning effect. The extension and retraction are controlled by the telescopic rod 9, which makes the scraper 11 fit against the filter cloth on the inner wall of the drum 2, thus achieving a good cleaning effect on the inner wall of the drum 2. Furthermore, a cleaning mechanism 12 is set on the centrifuge body 1 to clean the water tank 16 after the scraper 11 is withdrawn, thus cleaning the scraper 11 that has withdrawn from the drum 2 without manual cleaning, saving time and effort. The water tank 16 can be connected to an external air injection device through an air injection pipe to inject gas into the water tank 16, creating a high-pressure state in the water tank 16. This eliminates the need for a pump to provide power, and the use of high pressure to force water out has the advantage of being relatively fast.
[0027] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
